Mono- and Stereo- picture of 5.0 Angstrom coordination sphere 1 of Chlorine in the PDB 1ct1. Coordination sphere was calculated for all residues within 5.0 Angstroms distance from the central Chlorine atom, shown by VdW sphereResidues shown as a stick model or VDW spheres: H: Tyr12, H: His13, H: Hoh124,
